MACHINE FOR CUTTING WINDOW-STILE POCKETS.

SPECIFICATION forming part of Letters Patent No. 548,454, dated October 22, 1895. Application filed September 15,1892. Serial No. 445,959. (No model.)

To all whom it may concern.-

Be it known that I, FRANCIS V. PHILLIPS, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Machines for Cutting VVindowStile Pockets; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to machines for cutting pockets in window-stiles, and has for its object to provide a machine by means of which pockets with otfset top and bottom ends may be cut at these ends and also at the sides at a single continuous operation.

With this purpose the invention consists in a machine having two side cutters arranged to make the kerfs by which the pocket-piece is laterally detached from the stile, and two end cutters for each end of the pocket, the cutters of each of these pairs of end cutters being oifset and arranged to cut from opposite sides of the stile to a plane within the stile. These several cutters may be variously formed, variously mounted, and variously actuated.

In the accompanying drawings, which show one form of such a machine, Figure l is a plan view of the machine. Fig. 2 is a side elevation. Fig. 3 is a front elevation. Fig. 4 is a transverse sectional view taken on the line at at of Fig. 2 and looking in the direction of the arrows applied to said line. Fig. 5 is a central longitudinal sectional view of a window-stile, showing one form of pocket produced by the machine shown in the preceding figures.

In said drawings, A represents a frame adapted to support the remaining portions of the machine and provided with inclined end portions A.

B is the main or driving shaft of the machine, mounted transverselyin suitable bear ings B on the main frame A, and provided at one of its ends, which projects beyond the frame for the purpose, with an idle-pulley b, a driving-pulley b, and a fiy-wheel b Near its other end the shaft B is provided with a crank B to which is connected one end of a pitman C. The other end of the pitman is pivotally connected with a sleeve C, mounted to slide on a rod or shaft D, which is itself mounted in the main frame in the manner hereinafter described.

E Eare rods mounted to slide longitudinally in suitable guiding-sleeves e at each end of the machine. These rods are connected at suitable intervals by cross-heads E, each comprising a transverse body or web 6, collars 6 one at each end, to fit upon the respective rods E, to which they are secured by set-screws e or otherwise, and uprights e one of which extends upward from each collar 9 Three of these crossheads are shown in the present instance, although their number may obviously be varied as required. The uprights 6 form two parallel rows, each of which rows carries a saw or cutter F of suitable construction, the upper ends of the uprights being provided with suitable clamptug-jaws for holding these saws in vertical planes longitudinally of the machine, with their cutting teeth or projections uppermost and in a horizontal plane. One of the crossheads E is connected with the reciprocating sleeve C, and through this connection a simultaneous reciprocatory movement longitudinally ot' the machine is imparted to the rods E and saws F.

At or near the ends of the rods E, inclined bars E are attached to these rods, one at each end of the machine. Desirably, one of the rods E extends beyond the other at one end of the machine, while the other projects beyond the first-mentioned one at the other end of the machine to a corresponding extent. The connection between the bars E and rods E may be of any suitable naturesuch, for instance, as that shown, wherein the ends of the rods E are rabbeted to receive each a block 6 secured thereon by a clam p-screw a". Each block 6 has an aperture through which one end of one of the bars E passes, and in which it is secured by a set-screw 6 On each bar E is mounted a sleeve E adapted to slide thereon, these sleeves being secured to the opposite extremities of a longitudinal rod G. This rod G is provided near each end with a IGO transverse rod Cr, arranged at a right angle thereto and connected therewith by a setscrew g, or in any other suitable manner. The transverse rods G are mounted to slide in suitable guidingsleeves g, so thatthe longitudinal reciprocation of the rods E will, through the medium of the inclined bars E and sleeves E produce a simultaneous transverse reciprocation of the rod G.

Upon the rod G- are adjustably secured by means of set-screws or otherwise two sleeves 72, each of which is provided with suitable clamping-jaws to receive and hold a saw or cutter H. These saws or cutters are of any suitable construction-such, for instance, as that shownwhich will adapt them to cut in both directions of their movement, and are arranged to extend upward parallel with each other in an inclined position, which is also parallel with the inclined end portions of the frame A hereinbefore referred to.

Above the rod G is located asimilar rod G parallel therewith and supported and guided by cross-rods G located one near each end of the rod G, connected therewith by set-screws 9 or in any other suitable manner, and adapted to slide in guiding-sleeves g". The rod G has adj ustahl secured on it two sleeves h, each adapted to receive and hold a saw or cutter H, similar to the cutters H and arranged parallel therewith, the cutters H being, however, located in different planes from the cutters H, and with their cutting-edges directed downward.

The rod G has imparted to it a transverse movement of reciprocation simultaneously with but in the opposite direction from the rod G by means of two levers G one at each end of the machine, each of saidlevers being centrally pivoted at on the frame A or on a projection therefrom. At each of its ends each lever G is provided with a sleeve G pivoted at g on the lever, and the extended ends of the transverse rods G and G are bent, respectively, downward and upward to pass loosely through these sleeves, the end of the rod G passing through the lower one, while the end of the rod G passes through the upper one. By this construction it will be seen that the transverse motion of the lower rod G will be transmitted to an equal extent but in the opposite direction to the upper rod G and that while in transverse motion the rods G and G may either approach or recede. Suitable means are also provided for feeding the several saws or cutters to their work and withdrawing them from the kerfs. To this end the rod or shaft D is mounted in fixed bearings d at each end of the frame A, so as to be capable of a rocking motion in said bearings, and is provided at one of its ends with a lever D, by means of which it may be so rocked. Near each end of the rock-shaft D there is secured thereon, by means of a setscrew d or the like, a cross-bar D having in each of its ends a slot 61 Each of the inclined end portions A of the frame A is provided with similarly-inclined guiding-Ways,

these ways being shown in the present instance as rods or bars I, secured in lugs a projecting from the frame. At each end of the machine there are mounted to slide on these v ways two frames J and J. The frames J are arranged within the frames J and carry the guiding-sleeves e of the rods E and also the guidingsleeves g of the transverse rods G, which carry the rod G. Each frame J is provided with a pin j, and these pins extend through the slots 61 in corresponding ends of the cross-bars D The frames J surround the frames J and carry the guiding-sleeves g of the transverse rods G which carry the upper rod G Each frame J is provided with a pin j, and these pins engage the slots d in the ends of the cross-bars D opposite to those engaged by the pins j of the frames J. it will thus be seen that by rocking the shaft D the frames J and J and the saws carried thereby may be caused to approach and recede from each other in the plane indicated. It is in order to accommodate this motion that the ends of the rods G and G are passed through and slide within side sleeves pivoted on the lovers G instead of being directly pivoted to said levers. For this same purpose the connection between the sleeve C and cross-head E is a sliding one. In this sliding connection a plate 0 extends upward from the sleeve 0 parallel with the ways I, and is slotted, as shown at c in Fig. 4:. From the cross-head E a similarly-inclined plate 0 extends downward and is connected with the plate a by means of screw-bolts 0 passing through the slot 0 and screwing into the plate 0 v The material to be operated upon is held stationary, and this may be done in the following manner: The frame A is provided with a horizontal table or rest A having a central aperture a, through which the lower cutters work. Lateral guides K rest on this table and hold the work laterally in position, being adjustable toward and from each other and being held after adjustmentby means of suitable clamps k. Above the table A there is mounted in the frame A a transverse rockshaft L, provided with an arm Z, by means of which it may be actuated, and upon this rockshaft there are secured, one at each side of the aperture a in the table A two eccentric sectors or cams L, each provided with a slot Z concentric with the cam-surface and eccentric with relation to the shaft L. On each side of the aperture a there is located a clampingplate M, having a bolt m passing through the slot Z and also having a bearing-block m on which the cam-surface of the sector L bears. It will be at once seen that by rotating the rock-shaft L in one direction or the other the clamping-plates M may be caused to approach or recede from the table A to clamp the material thereon or release the same, as may be desired. The invention is not, however, limited to this particular form of clamping meananism, as it is obvious that other suitable mechanism for the purpose may be substituted therefor.

In order to render more clear the operation of the machine, there is shown in Fig. 5 a sectional view of a window-stile showing one form of pocket which the machine is adapted to produce, the same forming the subject-matter of an application filed by me October 21, 1891, upon which Letters Patent No. 483,968 were issued October 4, 1892, although the form of pocket shown in the present instance is a slight modification of the form shown in the drawings of said application. In the present case the stile N has formed in it a pocket N, having continuous side walls 02, parallel with each other and formed by the longitudinal saws F, and indirect end walls, each comprising two offset parallel and inclined portions it n and an intermediate portion 02 parallel with the surfaces of the stile. The portions n are produced by the cutters H and the portions 92. by the cutters H, while the intermediate portion n is produced by splitting out the pocket-piece. lhe machine as organized operates to do this work in the following manner: The material to be operated upon is clamped upon the table A and rotary motion imparted to the shaft B, which, through the pitmau O and sleeve C, causes longitudinal reciprocation of the rods E and cutters F carried thereby. At the same time the rods G and G carrying the cutters H and H, are reciprocated laterally through the connecting mechanism described and provided for that purpose. At the same time the cutters F and H are fed upward through the aperture a of the table A into the material from below, while the upper cutters H are fed downward into the material at an equal rate. This feeding movement is produced by rocking the shaft D by means of the lever D, which, through the medium of the slotted cross-bars D will move the frames J upward and the frames J downward simultaneously and to an equal extent. The transverse cutters H II are desirably so arranged as to each cut through slightly more than onehalf of the thickness of the material, so that their cuts overlap to a very slight extent. The cutters F cut entirely through the material. The cutters F are therefore, in the ma chine as here organized, adjusted with their edges above or more advanced than the edges of the cutters H, so as to complete their out entirely through the stile when the cutters H shall have advanced only part way through the stile. In other words, the cutters F enter the stock before the cutters H do so, and the cutters H and H enter the stile at about the same time. When the cutters have finished their cut, the lever D is used to rock the shaft D in the opposite direction and thus withdraw the cutters from the material, when this lattcr may be unclamped and Withdrawn from the machine. The pocket-piece will be finally detached by splitting the intermediate portions between the cuts of the transverse cutters by a sharp rap of a hammer or other suitable tool, as set forth in my prior application hereinbefore referred to. By adjusting the cutters H and H the dimensions and form of the pocket may be varied. By bringing the cutters H H nearer to each other than the cutters H H, so as to out between the line or cut of these latter, the particular form of pocket shown in my said prior patent may be produced.

Various modifications in the details of con struction may be made without departing from the principle of the invention. For instance, the form of the reciprocating frames or carriages which support and impart movement to the cutters may be other than that shown, the rod or bar frame with guidingsleeves Which I have devised being a convenient and inexpensive form which is shown merely for purposes of illustration; nor is the inclination of the transverse cutters essential, although in most cases desirable, for itis manifest that these cutters may be vertical, and the correspondingly-inclined other parts of the machine will then be also vertical. Moreover, the specific forms of actuating and connecting mechanism may obviously be varied, the same not being an essential part of the invention, which is not limited to the particular details shown and described.
